SUMMARY

Geomagnetic storms affect both the Northern and Southern Hemispheres, with aurora activity often appearing as a mirror image at the poles. The misconception that these storms only impact the Northern Hemisphere is incorrect. Satellite photographs have documented auroral displays at both poles, indicating that geomagnetic storm effects are global rather than hemispheric. Understanding the nature of Earth's magnetic field is crucial for comprehending these phenomena.

PREREQUISITES
  • Understanding of geomagnetic fields
  • Familiarity with auroras and their formation
  • Knowledge of satellite imaging technology
  • Basic principles of geomagnetic storms
NEXT STEPS
  • Research the mechanisms behind geomagnetic storms
  • Explore satellite imaging techniques for aurora observation
  • Study the effects of geomagnetic storms on Earth's atmosphere
  • Investigate the historical data of auroral activity at both poles
USEFUL FOR

Scientists, educators, and enthusiasts interested in atmospheric science, space weather, and the study of auroras will benefit from this discussion.

Hi all,
I have a question regarding geomagnetic storms:
--why always they affects the Northern Hemisphere?
Or did i got this idea wrongly?
Thanks
 
Earth sciences news on Phys.org
They are most noticeable at the poles [both poles], since that is where Earth's magnetic field originates.

yup you did :wink:
but that's OK you have come to a good place of learning :smile:

it has been seen by orbiting satellite photographs over the years that aurora activity at the North and South Poles ( caused by geomagnetic storming)
can often be an almost mirror image of each other.

I used to live in southern New Zealand and from a young age viewed and photographed many aurora
have a look here for some of my pics

just out of curiosity, where did you get the idea that they only affect the northern hemisphere ?
something you read or heard ?

cheers
Dave
